The apparatus comprising the invention embodies an outer shell or body indicate-d in general by the numeral 1 within which is located the well for the impure water to be distilled, the trough tor collecting the distilled water, and removable condensing medium upon the walls or surfaces of which the generated vapor is to be condensed. The shell or body` l comprises side walls 2, end walls 3 and 4, and a bottom which constitutes also the bottom of the well. ot the apparatus7 indicated by the numeral G, and

rinto which the impure water to be distilled is to be automatically fed as will be presently described. The said bottom 5 is preterably of the corrugated form illustrated most clearly in Figure 2 ot' the drawings so that it presents a heating surface of maximum area. and thus increases the eiliciency o't the apparatus in generating water Vapor or steam. Each ot the side and end walls oi the shell or body l compris-es inner and outer wall sections 7 and 8 suitably united at their upper' edges, as at 9, and spaced from their upper edges to a. point a suitable distance above the bottom 5 where the outer section 8 is brought inwardly at an angle,

`as at 10, and thence downwardly in a plane the lower portions of the wall sections 7 and S being prelieably tilled with asbestos or other suitable heat non-conducting inateiial 12. However the upper portions of the said side and end walls are of the hollow construction illustrated iii Figures 2, l and 11 ot' the drawings as to provide z. cold vater space 13 completely siirroiiiidlingthe interior orI the shell or body 1.

The iippe` portion of the well G is delined by a rectangular receiving; trough indicated in gene al by the numeral 14; and cour prising upstanding side and end walls 15 and 16 and a bottom wall 17, the walls 15 and 16 being spaced inwardly trein respective side and end walls ot the shell 1, and the bottoni wall 17 forming' a juncture with the inner sections 7 of the said side and end walls of the shell. The trough is open atits top and the walls 15 and 16 thereof preferably have their upper edges beaded, as indicated by the niinreral 18. lt will now be observed that the heat insulated lower portions oi the side and end wzlls ot' the shell 1 are ot a` height equal substantially to the depth oit the well 6 whereas these walls above the top olf the well are ot the hollow construction previously described and providing the warcrsjace 13. lf desired, the sections 7 and 8 ot the side and end walls ot the shell 1 inay be relatively braced in any suitable manner as lor example by tubular or solid spacing; eleiiiei'its 19 riveted or cured in place and extendingv between the said sections within the water space 13.

Tater is supplied, iu the nianuer to be presently pointed out7 to the water space 13, and in order that water inay be delivered liroin this space into the well G .i'here, by the application olI heat to the bottonil 5 ol the well, it is converted into steam and in oi der furthermore that. the water the well may be kept at a constant level and autoinati ally replenished, e float-Controlled valv provided a d will now be described. nieral 2O indicates in general which is inounted in adiiiiid-tigrht iiiaiiner upon the outer side ot the end w iall il ot the shell 1 and which coinprises side walls 21, a front wall 2?, and a bottoni 23, the said reservoir in horizontal section beingY preierably rectangular. A. ifiater delivery tube a is rigidly supported within the reservoir i iprig'ht position by suitable braces 25 or any other nianner found convenient a has in communication with it a branch which con'iiniinicates likewise with th space 13 within the said end wall ffi upoer end ot' the tube projects above t top ot the reservoir 2O and is closed by a cap 27 preilerably threaded ou to its upper end. At a point suitably spaced above its lower end, the tube 211- is provided interi rly with a conical or tapered valve seat 28, and

the iniineral 29 indicates :in elongated valve body of corresponding` torno which adapted to lit the seat Q8 so as to close 'the tube wh yn the valve is elevatedn and thus ire-,wut deli y of water through the tube to the reservoir 20. rlhe valve .is threaded at its lower end, :is at 30, iiito a suitably toriued i-:orliet 31 provided in the upper side ol' a iloat 3Q located within the reservoir fl() below the lower end or the tube 91, this lloat being` preferably oit rectangular l'orni so that by engagement with the walls ot' the reservoir it will be prevented troni turning' in the event the valve 29 is rotated to iinthread it troni its socliet 31. ln order that the valve inay be guided and also iii orner that inay be rotated for the purpose ot separatit Ylroni the float, it is provided at its upper lend with a stein 33 which extends iipwardly through the tube Q4 and is ot such length that its upper end will project to or above the upper end o'l the said tube eren when the float 32 is resting' upon the bottoni 23 ot the reservoir 2O so that its said upper end inay be gripped by a pair of pliers or the like for the purpose stated. Likewise th cap 27 is of a height sutlicient to aeeoininodate the upper cud ol the valve s'eni when the float 32 and valve li. ,in

lll

are elevated to such position that the valve will tit its seat Q8. ln order that water inay be freely delivered troni the tube the said tubeis not only open at its lower end, but i," also provided below the valve seat Q8 with a niiinber of water passages or openings El. lt p eterable that a wire or the liken iiidi cated by the numeral 35, be soldered or otherwise secured in a horizontal plane to `the inner sides olE tie walls ot the resei' *oir Q0 so as to indicate the proper water level whiel .should be n aintained within the appa x:dus i short tube 3? is litted through the lower portion ol the end wall Ll and establishes communication between the lower portion l the reservoir 20 and the well.

per edge oit' the front wall E22 of the reservoir 20. The said cover members are cut away at their meeting edges, as indicated by the numeral 411, so as to accommodate the projecting upper eud portion ot the tube i241, and the edge ot' one member as lor example the member 3T is 'irovided with an upstaudY ing lougitiulinal tiange 42 overiai'iped by an overturned flange vl-i `termed along the mecting edge ot the other mel'nliier 33. The memw bers 3T and 3S arc also preterably provided at their end edges with depeinliug V[lances indicated respectively by the numerals l-l and Ll5 which are designed to lit over the upper portions ot the sidewalls 21 ot the reservoir. rlhus the top ot the reservoir is closed in substantially a steam-tight manner for the purpose stated.

In order that water may be drained from the well G whenever required. without tho necessity ot invertingthe shell or body 1, a drain pipe 1G is led tl'n'ough the lower portion ofthe wall l of the said shell and is normally closed by a cap el? threaded onto its upper end, a packing gasket 8 being provid-ed within the cap to close the outer or discharge end oi' the said pipe 46 in a liquidtight manner.

In order that the steam or water vapor generated within the well 6 may be delivered therefrom and distributed 1over the surfaces of the `condensing medium, to be presently described, in the most effective manner, openings @and 50 are provided respectively in the side and end walls 15`and 16 of the receiving trough 11i a suitable distance below the upper edges ol the respective walls, and a cover 51 is provided for the top of the well as deined by the space surrounded by the said walls 15 and 1G. This top 51 comprises a plate 52provided with a marginal depending iiange 53 to seat over the beaded upper'edges 18 of the walls 15 and 16, and with a depending flange located inwardly ot the marginal flange 53 which flange 54 likewise lits tightly against the inner surfaces ot the beaded edges 18 of the said walls ot the receiving trough. By the provision ot this cover 51, the steam or water vapor generated within the well is trapped and caused to issue through the openings 19 and v5() and thus be discharged laterally rather than directly upwardly. However, the cover 51 is provided with any suitable number ot openings 5o distributed in a selectedway over the surface or the plate 52 and through which openings the steam or water vapor' is likewise discharged ina general upward direction.

Preferably the side walls 15, and it de sired also the walls 16, of' the receiving trough lll are braced with relation to the corresponding walls ot the shell or body 1 by means ot cross braces 5G preferably in the nature ot strips secured in any suitable manner at their ends to the said walls and extending between the same transversely ot the trough. Also it is preferable that the trough be supported by small upright-s 5l' which project upwardly from the bottom 5 oi the shell l and support the tour inner cornes*I or the trough. lt will be understood, however, that the trough may be reinforced and supported or braced in various other vv'ays it' tound desirable.

'W condensing medium heretoit'o're relne terred to is indicated in general by the nu nier-al D8 and the same is in the form ot a tank ot peculiar' construction into which water at a low temperature is caused to flow and in such a manner as to most eltectually cool the wallsv or surfaces ot the tank and thus condense the water vapor generated within the well ot the apparatus and directed against these walls or surfaces. The said tank 58 comprises sine walls 59, end walls Gl), and a bottom which is indicated iu general by the numeral G1 and which comprises upwardly inclined side Jortions 62 and upwardly inclined end portions (S33, the side portions 62 meeting in a ridge het, and the upper ends ot the end portions (32E terminating at the ends oit this ridge. 'llhus the said bottom is substantially ot a pyramidal torni and it projects upwardly into the interior ot the tank a considerable distance, Likewise it will be observed by .reference to Figures 2 and l ot the drawings that the side walls 59 ot the tank are inclined downwardly toward each other as are also the end walls 60 so that these walls occupy planes gradually diveiging in a downward direction trom the vertical planes occupied by the respective side and end walls ot the shell 1. Theretore there is provided between the walls ot the tank and the walls olf the shell a steam space which is indicated by the numeral and within which space the steam generated in the well ot the apparat may arise and by Contact with the relatively cool walls o1 the tank and shell, be condensed and drawn into the trough 14, the condensate trickling down the sides ot the walls of the tank and bony and trom the meeting lower edges ot the walls of the tank and the side and end portions ot the bottom oi" the tank. lt will also be evident that due to the peculiar form given the bottom o1 the tank, a steam space 6G is provided within the said bottom and immediately above the top ot the well (i. It will also be observed by ret'erence to Figures 2 and l oil the drawings that the meeting lower edges oit the walls ot the tank and bottom are ln order that the condensing tank 58 may be supported or suspended within the shell or body 1, the said tank is provided exteriorly near its top with a circumscribing horizontally outstanding supporting` flange G7 preferably having a dcwnturned outer marginal portion G8, this flange resting upon the top of the walls 2, 8, and l of the shell 1 and with its downturned margin 68 fitting snugly against the outer' sides of these walls so as to provide a substantially steam-tight connection between the partsn As stated the supporting flange 67 is located near the top of the tank 58 so that a portion of the tank projects above the top of the shell or body 1, and to this projecting upper portion of the tank there is removably fitted a cover which is indicated in general by the numeral (39 and which comprises a top 70 having a marginal portion 71 projecting downwardly at rignt angles and fitting snugly about the open top of the tank 58, from which portion 71 the margin oil' the top 70 is directed hori- :tontally as at 7 2, and thence downwardly as at 78 with the lower edge of this latter portion resting upon the upper side of the flange 67.

The manner in which cold water is continuously supplied to the tank 58 will now be described. The numeral 711 indicates a nozzle or valved inlet pipe which is in communication with the water space 13 within the end wall ft of the shell or body 1 and wl ',ch .may be connected with any suitable source of water supply. By this means water is permitted to flow into the water space 18 and to fill said space, a regulated volume of water overflowing into the reservoir 2O and from the reservoir into the well G. A short outlet pipe or nipple 75 is fitted through the top of the water space 13 at the top ot' the end wall 3 of the shell 1 and projects upwardly through a suitable opening (not shown) formed in the flange 67 of the condensing tank 58. The numeral 76 indicates the downward branching intake end of a water conducting pipe 77 which intake branch is disposed endwise to the upper end of the nipple 75 and connected in a water-tight and yet detachable manner thereto by means of a short piece of rubber tubing 78 or any other type of union. The pipe 7 7 has two downwardly extending legs or branches. The branches 79 and 80 eX- tend downwardly to one corner of the bottom of the tank 58 within the said tank, and the branch 81 leads from the lower end of the branch 79 along the adjacent end of the bottom of the tank 58, and a branch 82 leads from the lower end of the branch 8O along the adjacent side of the bottom of the said tank. Branches 88 and 84 extend along the other side and end respectively of the bottom of the tank 58 and are in communication with the branches 81 and 82 respectively and join each other' at the corner of the bottom diagonally opposite the corner at which the branches 79 and 8O are located. The several branches which are located within the condensing tank are formed with longitudinally extending series of perforations 85 and it will be understood that the several branches constitute a closed circulating system through which cold water flows from the water space 18 of the shell 1, the water being discharged in fine streams or jets through the perforations 85 and toward the walls of the tank 58 and its bottom 61. This supply of water is maintained even after the tank has become filled with water and therefore through the medium of said pipe system, cold water is supplied to the condensing tank in a manner to well up from the bottom of the same along the walls of the tank and its bottom and thus maintain the said walls and bottom at a relatively low temperature. An overiow pipe 86 is led through the projecting upper portion of one of the end walls of the tank 58 and may have litt-ed to it a suitable length of rubberl hose 87 to conduct the overflow from the tank to any suitable point of discharge. In order that sediment may be flushed from the water delivery pipe and its several branches above described, one of the branches as for example the branch 84 is provided with a short upwardly projecting nipple 88 which may be closed by a removable plug or the like indicated by the numeral 89.

1n order to adapt the apparatus for use in steam cooking food stuffs as for example in jars or other containers, a tray such as illustrated in Figure 5 of the drawings and indicated in general by the numeral 90 is provided and this tray is preferably in the form of a metal plate suitably reinforced at its margin, and elsewhere if desired, and provided with any desired number and arrangement of perforations 91 distributed over its area. lVhen the apparatus is to be employed for the purpose stated, the condensing tank 58 will be removed, the cover 69 separated therefrom, the cover 52 re moved from the top of the well 6, the tray 90 disposed in position resting upon the top of the well, as illustrated in dotted lines in Figures 2 and 1, and the cover 69 will then be fitted onto the top of the shell or body 1. l/Vith the apparatus thus arranged steam generated within the well will be discharged through the perforations 91 in the tray and about the containers for the food stuff being cooked.

In the event it is desired to cook food studs in containers which are to be partly submerged during the cooking operation, a tray indicated in general by the numeral 92 is disposed within the bottom of the well 6, the condensing tank 58 and cover 52 having been removed from the shell 1, and the containers :lor the lood stufimay be disposed upon this tray and within the well. l'he tray 92 comprises a plate all ol lrectangular lorni and olf dimensions adapting it Lo be litted downwardly through the top ol the well o and similarly removed therelroi'n, and this plate is preierably overturned or beaded and reinl'orced by wire, as at al at its niai-H gin. 'lhe plate oriiied with any suitable number and arrangement ol periorations 96 and thus 'the hot water may circulate lrecly past the plate and about the containers disposed thereon.

ln order that water distilled by the apparatus may be aerated during the distiiling operation and thus prevented l'roin acquiring the liat taste which is so noticeable in water distilled by ordinary methods, means is provided which will now be described. 'l'he numeral Sli' indicates air supply pipes each having a horizontal branch no leading;y

through the lower portion of one or another ol the walls ol the well t5, and a vertical branch J9 which leads upwardly :troni the inner end ol the branch Jo and through the bottoni ol the trough and upwardly into the trough a suitable distance. 'l`lie uppeil poi-tion ol each branch 9S) which is located within the trough is tormed with a number ol perliorations lull although the lower portion ol the branch Elli kwhich is located within the trough is imperlorate. 'ihus inasmuch as the branches 98 and elbows oit the pipes 9T are subjected to heat lroin the water being boiled in the well o, the air within the pipes will belieated and in rising will create a dralt or suction through the pipes resulting in a continual llow or, substantially cold air inwardly through the pipes and through the periorations 10U, the air thus discharged serving to aerate the distilled water accumulating in the trough. ln orde-i' that the outer or intake ends ol the branches 9&3 or the pipes 9i' may be closed when the apparatus is being employed solely as a cooker, the outer ends ol these branches are threaded and have litted thereto closure caps lul prei'- eiably connected by short chains or other ileizible connections 10:23 with the adjacentwalls ol the shell l so as to prevent loss when they are unthreaded l'roin the resped tive pipes.

By ieierence to Vlligures 2 and Ll ol the drawings it will be observed that the bottoni l? oi' the receiving trough le is inclined downwardly from the end ll to the end d o'l` the shell and at that portion ol the bottoni wall which is located neigt adjacent the end wall d of the shell, is sloped downwardly Yl'roni its opposite sides to a point n'iidway el its ends. A draw-oil' pipe il@ opens through the central portion ol this part ol the bottom wall of the trough and is led through the wall Ll of the shell and is provided with a valve or l'aucet 17') for controlling the liow ol' distilled water through the pipe. lt will lurtherniore be evident that because of the inclination ol the bottoni wall or' the trough and the introduction or' the draw-oil' pipe li at the lowest point in the bottom, the trough may be completely drained.

il cut--on` valve zo'd is preferably inter`- posed in the branch supply pipe 26, best shown in lliguie or the drawings, so as to control the supply olf water led to the reservoir 20, it being understood that this valve may be completely closed when desired, and the valve inlet le controlled so as to main tain a supply or' water in the boiling well or less volume than would be maintained through the automatic operation ol thelloa't controlled valve ZS). rlhus a relatively small volume or water may be maintained in the boiling .well Aso as to provide lor more rapid conversion or the water into steam and its subsequent condensation.

By reference to Figures 2 and d ol the drawings it will be observed. that the pipe interiorly ol the condenser 5B, is turned to extend downwardly at rigl'it angles at llo and welded or otherwise secured as at do to the inner side or the end wall 60 ol the condensing tank, the lower end ol this portion ol the pipe however being dellected inwardly as indicated yby the numeral 86 so as to provide ior the attachment ol a s it able length ol rubber hose Soc which leads downwardly to the bottom ol' the tank and which lorms one leg ol a siphon, the ilexible hose 8l' which is attached to the other end ol the over-flow pipe 86, constituting the other siphon leg and being led to any convenient point cl discharge. By this arrangement all ol' the water from the condensing tanli may be siphoned oil' without noise. A valve 8i" is interposed in the pipe et exteriorly ol the shell and may be ad* justed so as to maintain a water level in the tanli higher than the intake end 86h of the pipe 8G.

lt will be understood that the upper ends olf the branches 99 ot the pipes 9T are closed so to prevent distilled water dripping into these branches from the walls ol the condensing tank.
